Well, am to start writing driver for some dwc sata core in near
future, not sure of the
exact version because I've not yet had my hands on the specs.
Even if my version happens to be different, we don't wanna count on such odds.
So I believe it's worthwhile.

Btw, I presented two options and the author can always choose the
first one - rename
the driver as SoC specific. And in a way, I'd prefer that :)

Apart from increasing re-usability, that POV brings out neat code too.
